1 | ADS1015 (I2C) | ||
2 | |||
3 | This device is a 12-bit A-D converter with 4 inputs. | ||
4 | |||
5 | The inputs can be used single ended or in certain differential combinations. | ||
6 | |||
7 | For configuration all possible combinations are mapped to 8 channels: | ||
8 | 0: Voltage over AIN0 and AIN1. | ||
9 | 1: Voltage over AIN0 and AIN3. | ||
10 | 2: Voltage over AIN1 and AIN3. | ||
11 | 3: Voltage over AIN2 and AIN3. | ||
12 | 4: Voltage over AIN0 and GND. | ||
13 | 5: Voltage over AIN1 and GND. | ||
14 | 6: Voltage over AIN2 and GND. | ||
15 | 7: Voltage over AIN3 and GND. | ||
16 | |||
17 | Optional properties: | ||
18 | |||
19 | - exported-channels : exported_channels is a bitmask that specifies which | ||
20 | channels should be accessable by the user. | ||
21 | |||
22 | Example: | ||
23 | ads1015@49 { | ||
24 | compatible = "ti,ads1015"; | ||
25 | reg = <0x49>; | ||
26 | exported-channels = <0x14>; | ||
27 | }; | ||
28 | |||
29 | In this example only channel 2 and 4 would be accessable by the user. | ||
